Carranza pleaded guilty to two counts of first-degree robbery with sentencing enhancements for use of a gun. He was sentenced to 14 years in prison, Deputy District Attorney Jim Mendelson said.

Trinidad pleaded guilty to two counts of first-degree robbery and sentenced to three years in prison, Mendelson said.

On Dec. 23, three other defendants pleaded guilty.

Agustin Vazquez Velazquez, 28, Kain Espinoza, also 28, and Rocio Alejandra Badilla, 23, admitted going to an apartment complex in the 300 block of East Clifton Avenue where Luis Arreola was shot to death.

The April 2012 shooting occurred shortly after Arreola and Carranza went with a friend to Velasquez’s home in Montebello and stole three pounds of methamphetamine at gunpoint.

Velazquez and Espinoza pleaded guilty to conspiracy to commit a crime and admitted a sentencing enhancement for possession of drugs, Mendelson said. They are scheduled to be sentenced March 28.

Badilla pleaded guilty to extortion and was immediately sentenced to three years in prison, or the amount of time she has served in custody awaiting trial, Mendelson said.

Jose Felix Zepeda, 41, is considered the main defendant and is expected to go to trial next month on charges of murder, kidnapping for extortion, and conspiracy with sentencing enhancements for drug possession, Mendelson said.

Carranza, Trinidad and Arreola came up with a scheme to steal drugs from Badilla, Espinoza, Velazquez and Zepeda, according to prosecutors.

Trinidad told Espinoza and Velazquez she wanted to buy three pounds of methamphetamine that Zepeda had supplied, prosecutors said.

That same day, Carranza allegedly stole the drugs at gunpoint with Arreola and fled, leaving their friend behind.

Badilla, Espinoza, Velazquez and Zepeda forced the friend to drive them to Carranza’s apartment complex, took back the drugs and fled, according to prosecutors.
